    •  DETAILED DESCRIPTION
  • With reference to FIGS. 1-5, there is shown a supplemental medical gas system 10 for transferring medical gas, for example, oxygen, from a remote stationary bulk supply 14 to a spaced apart hospital medical gas conduit system 18 disposed in a hospital-type facility 22. Deployment of the system is essential during interruption of a permanent connection (not shown) between the remote supply 14 and the conduit system 18, such interruption being unexpected. Alternatively, the interruption may be one of planned maintenance or other reasons, such as inspection, when a temporary connection between the supply 14 and conduit 18 is necessary.
  • The system 10 generally includes a handcart 26 supported by wheels 28 to facilitate manual movement thereof via an upstanding handlebar 32.
  • The handcart 26 further supports a rotatable reel 34 which supports a hose 38 thereon in a conventional manner as shown in FIG. 2. The hose 38 has a preselected length to extend from the supply 14 to the conduit 18. Coupling fittings 42, 44, disposed on opposite hose ends 48, 50 are provided for connection to the supply 14 and conduit system 18 respectively. Berms 54 are provided for overlaying the extended hose, as illustrated in FIGS. 3 and 4 for enabling safe vehicle traffic over the hoses. The Berms 54 are conveniently stored on the handcart 26, when not deployed, as shown in FIG. 1.
  • As schematically shown in FIG. 5, the fitting 42 is attach proximate an on/off valve 58 which is part of the supply 14 and a second on/off valve 62 is provided and disposed proximate an on/off valve 66 to the conduit 18. The valve 62 enables a purging of the hose 38 with gas from the supply 14 in a conventional manner so that no contamination is introduced into the conduit 18 of the facility 22.
  • In that regard, a gas analyzer 70 may be provided for the determining purity in the gas in the hose 38 during purging.
  • Because the handcart 26 with stored hose 38 and berms 54 are conveniently and compactly stored near the facility, its deployment in a rapid manner during emergencies is facilitated. Also in that regard, wrenches and the like, not shown, for attaching and removing the fittings 42, 44 may also be conveniently stored in a toolbox 72 also carried by the handcart 26.
  • Thus, a method in accordance with the present invention for transferring gas from a remote supply 14 to a spaced apart hospital medical conduit system 18 during interruption of a permanent connection (not shown) between the remote supply 14 and the conduit system 18 includes providing the wheeled handcart 26 with a rotatable reel 24 for supporting a length of hose 38 with the hose having coupling fittings 42, 44 on ends 48, 50 thereof.
  • The method further includes connecting one end 48 of the hose 38 to the gas supply 14 via one of the couplings 42 and thereafter unreeling of the hose 38 as illustrated by the arrow 76 in FIG. 3 as the handcart is moved toward the facility 22 as indicated by the arrow 78 for deploying the hose 38 across and area 82 as illustrated in FIGS. 3 and 4 thereafter the another end 50 of the hose 38 is connected to the facility 22 conduit system 18 via the coupling 44.
  • Before fluid communication is established between the hose 38 supply 14 and conduit 18, the hose 38 is purged of air with the gas from the supply 14.
  • In the event the area 82 is a roadway, the method further includes disposing berms 54 over the hose 38 as illustrated in FIGS. 3 and 4 to enable vehicular travel thereover without damaging the hose 38.
  • During unreeling of the hose 38, a disk brake 86, controlled by a grip 88 disposed on the handlebar 32 via cable 90, provides for constant hose 38 payout. This prevents any undesired hose 38 overdeployment.
  • Although there has been hereinabove described a supplemental medical gas system in accordance with the present invention for the purpose of illustrating the manner in which the invention may be used to advantage, it should be appreciated that the invention is not limited thereto. That is, the present invention may suitably comprise, consist of, or consist essentially of the recited elements. Further, the invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein. Accordingly, any and all modifications, variations or equivalent arrangements which may occur to those skilled in the art, should be considered to be within the scope of the present invention as defined in the appended claims.
